More specifically, rise in the cusp 50 of plate-like piece 46 along with driven member 48 when first end 70 and when moving in the end 64 in aperture 62 of connecting rod 58 one, the primary importance of the first end 70 of a sensing cable 68 in sensor 86.From the cusp 50 of plate-like piece 46 one descends and when moving to another end in aperture 62 of connecting rod 58 along with driven member 48 when first end 70, the second place of the first end 70 of another sensing cable 68 in sensor 86.When the central point C place in the aperture 62 when first end 70 between first and second position and driven member 48 are arranged in of recess 52 of plate-like piece 46, two sensors 86 are the neutral position of the first end 70 of sensing cable 68 all, thereby realizes the suitable location in gear 36 one of shift member 34.If during the first end 70 that after another in plate-like piece 46 and driven member 48 move to gear 36, sensor 86 senses cable 68 is in the first and second positions one, sensor 86 transmits a signal to controller 30, realize suitable gear 36 thereby cause controller 30 to transmit a signal to actuator 22 in order to the current location of connecting rod 58 is adjusted to the another location, thereby prevent from damaging speed changer 32.In other words, if driven member 48 fails suitably to be arranged in recess 52 one, sensor 86 transmits a signal to controller 30 so, and described controller 30 transmits a signal to motor 24 so that mobile link 58, gear are selected lever 82, plate-like piece 46 and driven member 48, in order to driven member 48 is positioned at rightly in the recess 52 of expectation, thereby realizes suitable gear 36 and prevent from damaging speed changer 32.
Relative to each other mobile realize expecting in gear 36 one the time, whether sensor 86 sensing cables 68 are pushed or pull when plate-like piece 46 and driven member 48.Only for the purpose of illustration, the below will discuss the example that promotes or pull cable 68, and wherein sensor 86 is defined as first sensor 86 and the second sensor 87.This discussion is applicable to the variation between any gear 36.Consult Fig. 2, schematically show the plate-like piece 46 that moves through a plurality of gears 36 and driven member 48 and the first and second sensors 86,87 relative orientations with respect to described plate-like piece 46 and driven member 48 in figure.If user's expectation changes to reverse gear 42 with one in the gear 36 of speed changer 32 from Parking shelves 38, plate-like piece 46 and driven member 48 relative to each other move so, thereby wherein driven member 48 rises to a cusp 50 and causes first sensor 86 to sense cable 68 being pulled.After driven member 48 arrived the top of cusps 50, driven member 48 descended and the second sensor 87 senses cable 68 and is pushed from cusp 50.In case driven member 48 suitably is arranged in the recess 52 of reverse gear 42, the first and second sensors 86,87 all sense cable 68 and are not pushed or pull so, therefore realize suitable gear 36.
As another example, if user expectation changes to Parking shelves 38 with a gear 36 of speed changer 32 from reverse gear 42, the second sensor 87 will sense that cable 68 is pulled and first sensor 86 will sense cable 68 and be pushed so as shown in Figure 2.In other words, driven member 48 and plate-like piece 46 move around by gear 36 according to the gear 36 of request, and the first and second sensors 86,87 sensings promote or pull, and the gear 36 of request is positioned according to described motion mode.For example, first sensor 86 sensing driven members 48 are gone up cusp 50 when moving to reverse gear 40 from Parking shelves 38, and the second sensor 87 sensing driven members 48 descend from cusp 50 when turning back to Parking shelves 38 from reverse gear 40.
As shown in Figure 1, controller 30 can improve with following parts communication the safety operation of vehicle: actuator 22, switch 54, selector member 56, sensor 86, transmission sensors 84 and with related other sensors 86 of vehicle.For example, velocity transducer 93 can with controller 30 communications, the speed of described velocity transducer 93 senses vehicle.Speed limits by durection component and speed component.Controller 30 can determine whether to change a gear 36 in response to two in the direction of-at least part of speed in response to vehicle and speed component or any.Therefore, surpass predetermined speed if controller 30 is determined the speed of vehicle when gear 36 moves to another gear 36 from a gear 36, velocity transducer 93 will be with controller 30 communications in order to prevent from changing gear 36 so.For example, if vehicle be in forward gears 44 and surpass that predetermined speed is travelled and user's gear shift to Parking shelves 38, controller 30 will remain on forward gears 44 with this request of override and speed changer 32 so.In addition, controller 30 can with braking sensor 94 communications so that whether sensing brake pedal 96 be pressed down.Controller 30 can require brake pedal 96 to be pressed down speed changer 32 can change to any other gear 36 from Parking shelves 38 before.
